  • Patent number: 11280891
    Abstract: An underwater detection device may include a transmitter, which may include a transmitter, a receiver, and processing circuitry. The transmitter may be configured to transmit a transmission wave. The receiver may be configured to receive a reflection wave of the transmission wave. The processing circuitry may be configured to acquire a first position of a ship and a first measurement value that is a measurement result of the reflection wave at the first position, determine whether a relationship between the first position and a second position of the ship or another ship meets a given condition, and calculate a correction value based on the first measurement value and a second measurement value that is a measurement result of the reflection wave at the second position under a circumstance when the given condition is met.

  • Publication number: 20200158845
    Abstract: An underwater detection device is provided, which includes an echo signal processing module configured to acquire echo signals and detect signal levels of the echo signals corresponding to water depths, the echo signals being reflection waves caused by ultrasonic waves transmitted underwater, a detection image display controlling module configured to display on a display unit a detection image indicating the signal levels of the echo signals corresponding to the water depths and placed in a chronological order, and a menu display controlling module configured to display first superordinate menu buttons on the detection image displayed on the display unit, one of the first superordinate menu buttons displayed in one of end sections of the detection image where oldest information is displayed, the rest of the first superordinate menu buttons displayed to extend from the one of the first superordinate menu buttons in one of depth directions and time axis directions.

  • Patent number: 9602658
    Abstract: A marine wireless device includes a calling unit, a response unit, a communication establishment unit, a call processor, a condition memory unit, and a recorded data processor. The calling unit sends call information requesting the start of communication. The response unit sends response information with respect to the call information sent by a communication partner. The communication establishment unit receives the response information from the communication partner and establishes communication with the communication partner. The call processor executes a voice call with the communication partner with whom the communication establishment unit has established communication. The call memory unit stores as recorded data a voice call executed by the call processor. The condition memory unit stores specific data processing conditions related to recorded data. The recorded data processor varies the processing related to recorded data according to the data processing conditions.
